CeramicSpeed 17x30x7mm Bearing: superior performance with silicon nitride balls
The CeramicSpeed ceramic bearing is the ideal solution for those seeking ultra-low friction and maximum power transfer efficiency. Fully hand-assembled in Denmark, this bearing uses Grade 3 silicon nitride balls matched micron by micron with ultra-smooth hardened steel races. The ceramic balls are 400% smoother and 128% harder than standard steel bearings, ensuring exceptional performance in any conditions. The reinforced polyamide cage keeps the balls perfectly positioned, while the low-viscosity Blue Grease lubricant minimizes friction and significantly extends the component’s service life.
Universal compatibility and stringent quality control
This 17x30x7mm bearing is designed to fit any cycling discipline: road, time trial, triathlon, track, cyclocross and mountain bike. The non-contact seals effectively protect against dirt and moisture, maintaining performance over time. Every bearing undergoes four manual checks during assembly to ensure the perfect matching of all components. Compared with other ceramic balls on the market, CeramicSpeed balls are 15% harder, withstand loads that are 99% higher and offer 100% greater smoothness, confirming the product’s technical superiority.
Performance benefits and long-lasting durability
The use of lightweight ceramic balls reduces overall weight by 58% compared with traditional bearings, helping improve acceleration and the bike’s responsiveness. Low friction translates directly into better power transfer, allowing cyclists to make the most of every pedal stroke. The combination of premium materials and advanced manufacturing technology ensures superior durability, reducing the frequency of maintenance and replacement. This bearing is a long-term investment for those who refuse to compromise on quality and mechanical performance.
